The utility model is characterized in a drive gear fixed to the lateral sides of the large and the small carriages and surface teeth arranged on the lateral side of the steel rail are engaged, and the drive gear is driven by a driving device. Two lateral sides of the steel rail are working surfaces in order to guarantee the precision of the engagement, and at least one pair of horizontal wheels is respectively arranged on the two lateral sides of the steel rail of the large and the small carriages. All of the wheels of the crane are driven wheels, the wheels without wheel flanges are introduced to the large and the small carriages, and the digital control system and the transmission method of the engagement of the drive gear and a rack bar are adopted in the utility model. Two operating methods such as manual operation and automatic operation are adopted, the operation inertial force and the operation deviation of the crane can be decreased to a minimum value, and the operation precision can be raised to a maximum value. Multipoint point-to-point positioning control, random point-to-point positioning control and remote control are conveniently realized, the utility model has the advantages of advanced technology, preferable performance, simple structure and stable operation, and a lifting tool can accurately and smoothly run to the point of destination.
Description
[technical field] the utility model relates to a kind of super hoisting crane at a slow speed of accurately locating automatically, belongs to accurate weight-lifting equipment technical field.
[background technology] hoisting crane is widely used in every field, and in enterprise, the carrying of some objects and workpiece mainly relies on hoisting crane.But because hoisting crane generally is installed on the carrier bar, form hoist frame by end fine strain of millet and crossbeam, the dolly that comprises suspender is housed on the hoist frame, and the hoisting box is installed in the hoist frame lower end, the article of carrying transport out of chaufeur, and situation about causing the accident owing to misoperation happens occasionally.Especially under bad working environments such as high temperature, many dirt, inflammable and explosive, radiation, when commander's handling personnel can't carry out the ground control, judge with the range estimation of hoisting crane chaufeur experience entirely that M/C carries out handling, in case error will cause serious accident.
CN2478997Y has proposed a kind of crane hanger 3 D locating device; CN 2484295Y has proposed a kind of container spreader 3 D locating device.All these registration devices all are to adopt laser positioning, behind the laser positioning signal input single board computer (SBC), carry out automatic handling through the automatically controlled power system of single board computer (SBC) computing output signal control hoisting crane.Above-mentioned hoisting crane exists operation force of inertia and operation deviation owing to adopt the traditional wheel and the frictional transmission of rail, and the location of its registration device is difficult to reach automatically accurately locating effect naturally, can't satisfy the specific demand of some High Precision Automatic location occasions.
[summary of the invention] the utility model has overcome the deficiency of above-mentioned prior art, and its purpose is to provide a kind of super hoisting crane at a slow speed of accurately locating automatically.
The purpose of this utility model realizes by following technological means.
A kind of accurately the location automatically surpasses hoisting crane at a slow speed, comprise the big dolly and the operation driver train thereof that are installed on the rail, the operation driver train that it is characterized in that said big dolly is the transmission gear that is fixed on big dolly side, is driven by actuating device, with the face tooth engagement of rail side.
Processing for convenience, above-mentioned rail preferably adopts the rail of side inserted tooth bar, with the power wheel engagement of big dolly.In order to guarantee accuracy of mesh, the rail both sides are finished surface, and big or small parking stall respectively is equipped with at least one pair of horizontal wheel on rail two side positions.
Four big wheels and four trundles of the large and small car of this hoisting crane all are follower, have both born amount and load weight in self, and large and small car wheel adopts no wheel rim wheel.
The operation driver train of hoisting crane provided by the utility model, adopt driving cog wheel and rack engaged transmission mode, can make the operation force of inertia and the operation deviation of hoisting crane reduce to minimum, make running precision bring up to maximum, thereby guaranteed suspender accurately, smooth running is to object point, operating error horizontal direction (X-Y) is little and ± 1.25 millimeters; Vertical direction (Z) is not more than ± and 2 millimeters.Above-mentioned operation driver train can adopt digital control system and PLC system and digital servo drive to control, and has manual, automatic two kinds of operation modes, can realize multiple spot set point control and set point control at random easily.By man-machine interface, can realize distance control, so that to the crane current location, the present position, sense of motion, the target location, velocity magnitude is monitored.For summit at random, as long as the input coordinate value, this crane just can run to the target location automatically.This hoisting crane advanced person that possesses skills, superior performance, simple in structure, advantage such as stable, the huge market demand.

Introduce the utility model embodiment in detail below in conjunction with accompanying drawing.
[specific embodiment] as shown in Figure 1, 2, digital process control system is made up of man-machine interface and control housing in the present embodiment; The no wheel rim wheel 5 of big dolly is placed on the rail 7 of inserted tooth bar 8, and four big wheels and four trundles of large and small car all are follower, only bears amount and load weight in self; The operation driver train of big dolly adopts servomotor torque constant 2, and servomotor torque constant 2 drives the transmission gear 4 that is fixed on big dolly side, is meshed with the flank of tooth of inserted tooth bar rail 7.Dolly lifting mechanism 9 comprises suspender 11 and commutator 3, is placed on the crane span structure 10.In order to guarantee accuracy of mesh, rail 7 both sides are finished surface, and big or small parking stall respectively is equipped with two pairs of horizontal wheel 6 on 7 liang of side positions of rail.
The principle of work of this hoisting crane is as follows: establish in the crane job face by some summits, Getting Played one summit, pass through man-machine interface, with the quantitative data input computer, begin to send the operating instruction parameter behind the digital control system 1 lock onto target point, simultaneously to the crane current location to each mechanism, the present position, sense of motion, the target location, velocity magnitude is monitored.Operation servomotor torque constant 2 drives transmission gear 4 by commutator 3 and does engaged transmission with the tooth bar 8 that is embedded on the rail 7 according to the given operating instruction of coordinate X-Y value, thereby drives dolly 9 and crane span structure 10 operations.Hoist servomotor torque constant 2 according to the given operating instruction of coordinate Z value, and control is hung to lift and is risen decline, and deflection and offset deviation that hoisting crane and dolly produce when operation are controlled by horizontal wheel, and the gap of horizontal wheel and rail is less than 0.05 millimeter.
